[Pkg-utopia-maintainers] Bug#562811: network-manager: if-down.d should be dispatched before interface goes down (phase is "pre-down")

[Mark Hedges]

Package: network-manager
Version: 0.7.2-2
Severity: important


https://bugzilla.gnome.org/show_bug.cgi?id=605579

nm_device_state_changed() in src/nm-device.c waits until the interface goes
down to call nm_utils_call_dispatcher("down",...).  

As a result, scripts in /etc/network/if-down.d do not have access to the
network when they run.  (Try putting a script in the if-down.d directory that
runs "logger 'NM DEBUG' `ifconfig $IFACE`" and you will see in the syslog that
the interface is down.)

This is incorrect, because it does not conform to the behavior of ifupdown, and
because many packages install scripts in if-down.d that expect the network to
be available.  (For instance, I might want to install a script that sends my
log-off time to a remote server, ships out logs of what I've been doing, etc.)

I tried changing nm-device.c to put the "down" dispatcher call just after
caching the activation request, but that did not help - the interface is still
down when the scripts run.

if-post-down.d is supposed to be for running the "post-down" phase.

Tons of other people and packages have depended on the consistent behavior of
standardized pre-up, post-up, pre-down and post-down PHASE values.  It is not
fair to the larger community for RedHat engineers to change this to disrupt the
behavior of other flavors of Linux.  (if-pre-up.d and if-post-down.d is bug
number 600167 at https://bugzilla.gnome.org/show_bug.cgi?id=600167)

Thanks.  --mark--
